RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 421,359, dated February11, 1890. Application filed December 6, 1886. Serial No. 220,769. (Nomodel.) Patented in England June 16, 1882, N0. 2,838.

To all whom it may concern:

Be it known that we, GEORGE PERKINS, GEORGE WIMPENNY, and JOSEPHI-IAMPsoN EVANS, all of Manchester, in the county of Lancaster, England,and subjects of the Queen of Great Britain and Ireland, have invented anew and useful Improvement in Ring-Spinning Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

We have obtained British Letters Patent thereon, No. 2,838, dated June16, 1882.

In order that our invention may be understood and carried into effect,we will describe the same by reference to the drawings here withannexed, in which Figure 1 is a front view of such portion of a ring,ringrail, bolster-rail, bolster, and spindle as is requisite toillustrate our invention. Fig. 2 is a side view, partly in section, ofthe parts shown in Fig. 1. Fig. 3 is a plan of a portion of the partsshown in Fig. 1. Fig. 4. is a front view, and Fig. 5 a plan, showing aform of traveler constructed according to our Fig. 6 is a plan of a ringwith a traveler constructed according to a modification of ourinvention. Fig. 7 is a section showing a modified construction of aring. Fig. 8 shows a modification of the construction shown in Fig. 1,and shows a front view of so much of a ring, ring-rail, bolster rail,bolster, and spindle as is requisite to illustrate our invention. Fig. 9is a side view, partly in section, of the parts shown in Fig. 8. Fig. 10is a plan of a portion of the parts shown in Fig. 8. Fig, 11 is a sideview of a traveler shown in Fig. 10. Fig. 12 is a plan 01": the saidtraveler. Fig. 18 is a plan of a ring with a traveler constructedaccording to a modification of our invention.

We shall apply the same letters of reference to correspondingpartsthroughout the whole series of figures.

In Figs. 1, 2, and 3, o. is a portion of an ordinary spindle, which ismounted so as to be capable of being revolved in a bolster or collar b,which is secured to a bolster-flail. o in the ordinary manner. The ring61 is shown as mounted in a clip 6, the ends of which clip 6 passthrough the lifting rail f and are secured in the lifting-rail f by thenuts g; but the rings d may be secured to a ring-rail of any suitableform or construction in any suitable manner.

In the ring d is formed an internal groove or recess h.

The traveler j is made of steel wire bent into the form more clearlyshown in Figs. 4 and 5, Fig. 4: being a side view of the traveler, andFig. 5 a plan thereof. One end of the wire forming the traveler is bentinto a hook j, and a part intermediate between the ends is bent to forma yarn-guide j The parts 7 j of the traveler j, which rotate in thegroove or recess 71, are curved or bent, as shown, to impart steadinessto the traveler and to furnish sufficient wearing-surface. The end 7' ofthe traveler j, instead of being curved or bent, as shown, may be madestraight. The hook j may be made as a circular eye or curl, and theyarn-guidej may also be slightly varied in form. The traveler j issprung into its position within the groove or recess h, the insertion ofthe traveler j into the groove or recess 7L being facilitated by thecurved form of the traveler j.

The sliver or yarn in passing from the drawing-rollers to the spindlefirst passes under the hook j of the traveler j, and then passes on toand partially round the yarnguidej of the traveler j, and then passes tothe spindle, on which it is wound in the form of a cop.

From the foregoing description it will be readily understood that thetraveler, while rotating in the groove or recess h of the ring d, isfree to adjust itself to or be controlled by the tension of the yarnpassing from the travelerj to the cop, such varying tension resultingfrom the varying diameter of the conical part of the cop upon which theyarn is being wound. Thus when winding 011 the smallest diameter of thecop, at which time the tension of the yarn would otherwise be excessive,the traveler yields to the pull of the 5 the traveler tends to equalizethe tension upon the yarn bein spun or doubled.

the ring d.

In Fig. 6 is shown a modification of the traveler j, the traveler beingpunched or stamped out of sheet metal. By adopting this form of thetraveler we obtain an increased area of wearing-surface at the partswhich run in the groove or recess 72-. e pre fer to harden both therings and the travelers.

Fig. 7 illustrates another form of construction of the ring d. In thisexample said ring is formed in two parts d d the groove or recess hbeing so formed that the traveler j rotates on narrow surfaces or ridgesh 72, formed in the part of the ring which is nearest the spindle. Bythis means the friction due to the rotation of the traveler is reduced.-

Figs. 8, 9, 10, and 13 show another modification of the ring d. The ringis shown as constructed in two portions, of which one is a cap formedpreferably of steel and secured to the ring-rail Z by means of thescrews m and n, which pass through holes in the cap it. In the cap it weform a circular recess A, within which and resting upon the ring-rail Zis a ring 0, which forms the other portion of The ring 0 is formed ofsuch thickness that a space A is left between the upper edge or ridge 0of the ring 0 and the ridge 7c of the cap 76. In this space A thetraveler j rotates. \Ve form the upper surface of the ring 0 conical, sothat any dirt from the ends of the traveler 3' may pass to and escapethrough openings p q, formed through the sides of the cap 70. The holesin the cap 7t, through which the screws m and a pass, being larger thanthe diameters of these screws,

permit of the adjustment of the cap 7c and ring 0 so as to be concentricwith the spindle a, in which position the cap it andring 0 may besecured by the screws mand n. The cap 70 and ring 0 may be removed fromthe ringrail Z and from each other for cleaning or other purpose uponthe removal of the screws m n, and afterward the cap 70 and ringo may beagain secured in their working position upon the ring-rail Z.

The cap 7t and ring 0 together form a ring d, which supports and guidesthetraveler placed therein in a manner precisely similar to that inwhich the ring d, previously described in reference to and shown byFigs. 1 and 6, inclusive, supports the traveler j placed therein.

It will be seen on reference to Figs. 1, 2, 8,

and 9 that the lower end I) of the bolster or collar b is extendeddownward to the warve, whirl, or pulley 7', fast on the spindle a. Agrooves is formed in the outer surface of the end Z) of the bolster orcollar Z), and the upper flange of the Warve, whirl, or pulley 1' ismade smaller than usual, so that the drivingband can be readily slippedout of the groove in the warve, whirl, or pulley rinto the groove 8,formed in the lower end 5 of the bolster or .collar Z), whenever it isdesired to stop the spindle a. By this means we are enabled to stop asingle spindle Without arresting the motion of any of the otherspindles.

The traveler shown in Figs. 11 and 12 is i like that shown in Figs. 4and 5, except that the portion j is not curved, except at its upper end,where it is bent in the form of a hook. In Fig. 13 the traveler is thesame as that shown in Fig. 6, with the exception just I referred to indescribing the traveler shown in Figs. 11 and 12.

W'e claim I 1. The combination, with a spindle, of an internally-groovedring through which said spindle extends, a longitudinally-bent travelerhaving its end portions extending into said groove, one of said endportions being bent round and having an upwardly-extending hook, and ayarn-guide on said traveler, substantially as specified.

2. The combination, with a spindle, of an internally-grooved ringthrough which said spindle extends, a longitudinally-bent traveler madein one piece and having its end portions extending into said groove, oneof said end portions being bent round and hav ing an upwardly-extendinghook, and ayarnguide on said traveler,substantially as specified.

3. The combination, with a spindle, of a bolster through which saidspindle passes and a warve upon the spindle below said bolster, saidbolster adjacent to the said warve being provided with a circumferentialgroove, substantially as and for the purpose specified.
